More than 1,000 people filled Temple Aliyah in Needham Tuesday for the funeral of Talia Newfield, one of the two teenagers who died after being struck by a car on Saturday.
Dozens, perhaps hundreds of teenagers attended the two-hour service, said Rabbi Carl Perkins.
“It was moving to hear the many people who spoke about their appreciation and affection for Talia,” he said.
Newfield was buried at a West Roxbury cemetery, said Perkins, and her family is also planning a memorial observance at a later date.
Newfield, 16, and her friend, Adrienne Garrido, 17, were fatally injured around 5 p.m. Saturday while trying to cross Webster Street near Needham High School.
Newfield was taken to Beth Israel Deaconess Hospital-Needham and pronounced dead Saturday; Garrido was transported to Beth Israel Deaconess Medical Center in Boston, where she died of her injuries Sunday, officials said.
The investigation into the deaths of the two teenagers is active, and no charges have been filed in the case yet. A spokesman for Norfolk District Attorney Michael Morrissey said law enforcement is keenly aware that relatives and friends want to know how and why their lives ended so suddenly.
David Traub, Morrissey’s spokesman, said fatal crash investigations by the State Police CRASH unit are exhaustively detailed, and it takes time in order to provide a thorough account of any fatal crash.
“It’s a technical process, a methodical process,’’ Traub said. “It’s not unusual for the results to be measured in weeks.”
A recent fatal crash — the Nov. 19 death of a 6-year-old boy — did not generate evidence supporting criminal charges until Feb. 6, or about two and a half months. Traub said an investigation can take longer if outside expertise is requested or complicated forensic testing is required.
The drivers of a Cadillac sedan and a Nissan Sentra involved in the Needham accident stopped after the crash and were interviewed by police, officials have said. Without explicitly stating an investigative conclusion, Traub noted that arrests at a crash are most often linked to alcohol or drug intoxication — and neither driver was arrested by police last Saturday night.
The Newfield family said in a statement released by the Needham schools this week that they wanted to “thank our friends, family, synagogue, and many members of the Needham community who have reached out and given to us their support, and their love.”
The statement said, “Adrienne and Talia were two beautiful, close friends and awesome young women with their whole lives and world ahead of them. We simply don’t understand how they could have been taken from us while crossing a flat, straight street in the heart of Needham. Life does not always make sense.”Danny McDonald of Globe staff contributed to this report. Emily Sweeney can be reached at email@example.com. Follow her on Twitter @emilysweeney.
